Could I have pressed charges against my gym teacher in high school?

The statute of limitations is up on this one, I don’t care now, and I didn’t care when it happened. I’m simply curious if I could have pressed charges against my high school gym teacher for an incident that occurred when I was 15.

BACKGROUND:
I went to an all-girls private Catholic high school, so of course my gym class was all female. The gym teacher was female as well.

THE STORY:
One day, after I had changed out of my uniform and into my gym shorts, the teacher yelled at me for rolling them up and making them too short. At the time, I was standing in front of the group of girls in my class with my back to them.

The female gym teacher walked over to me in anger at the length of my shorts and yanked them down. I believe she was only attempting to pull them down a few inches so that they would be an appropriate length, but instead, she pulled them all the way down to my ankles.

I was wearing a thong, and all of the girls in my gym class got a nice view of my butt.

I didn’t care at all; I just laughed. But the gym teacher was unbelievably embarrassed. She was like, “Oh, oh, god. Oh, I am so sorry. Oh my god, I am so sorry,” and she turned bright red and walked into her office.

CONSEQUENCES?
If I had been offended or upset, what could I have done? What possible consequences could she have faced for this behavior? Could she have been fired? Arrested? Sued? What is the worst that could have occurred if I had wished to make her pay for this incident? Would I have had to go to court for it?

I’m just randomly curious.
